Abstract: Provided is a construction machine that enables to reduce the burden of the operator when the operator replenishes a liquid reducing agent. The construction machine includes an upper frame slewably provided on a lower traveling body, a reducing agent tank provided on the upper frame, and configured to accommodate therein a liquid reducing agent for reducing nitrogen oxide contained in exhaust gas, and a passage surface provided on the upper frame for allowing the operator to move to an engine. The reducing agent tank has an upper placement portion disposed on the right side of the passage surface at a position higher than the passage surface. The upper placement portion of the reducing agent tank has a replenishing port for allowing the operator to replenish the liquid reducing agent. The replenishing port is provided so as to face the passage surface.
